smart water leak detector

I had a costly leak under my dishwasher that went unnoticed until it was too late and caused damage to the ceiling below. The ceiling had to be replaced entirely, as well as the insulation that was ruined by the water damage. To add to the pain, I had to purchase a new dishwasher since it was the source of the initial leak. All in all, this cost me around 4000 dollars in repairs and replacement of materials.

Of course, I could have avoided such a considerable expense if I had known about the leak when it first occurred. A Smart water leak detection system would have been beneficial in my case. These devices are relatively small, with prices ranging from $50 to $ 100 each, and they detect any water leaks before severe damage is done to your property.

Having a smart home has many benefits. One is preventing water damage, as I experienced with my dishwasher. Smart water detectors are affordable investments compared to costly repair bills that these devices could have easily prevented if installed beforehand!

Your home is more likely to suffer water damage from a Plumbing fixture than a flood

I was surprised to learn that domestic water leak is the number one cause of water damage, not floods. For a long time, I thought smart water leak detectors were for homeowners in areas prone to flooding. But after learning that anyone can come home to an indoor swimming pool (wet floors) because of a leaking fixture, I am convinced smart water leak detectors are for everybody.

But finding the best water leak detector is a hassle since many substandard sensors are on the market. I bought and tested some sensors to see if they were up to the task. I even paired the water sensors with accessories I bought separately to shut off my main water supply and see the results.

Smart Water Leak Detectors Buying Advice

You want to first understand the causes of a fixture leakage before buying a smart water leak detector. I discovered that extreme temperatures are the number one cause of fixture leaks. Specifically, freezing temperature causes water expansion that bursts the pipes. 

Whatever the cause of a leak, you want to buy the best smart water leak detector to detect leakages and repair the fixtures fast. But you will need to consider a few factors when shopping. I have compiled the things to look at when shopping for a water leak sensor. Here are some things to consider:

Water Leak Detection Sensitivity

The sensitivity and responsiveness of a smart water leak detector are the things to consider first. You want a responsive smart water detector that alerts you to a water leak way early before severe damage. My Moen Smart Water Detector responded when water was a few inches from its sensors.

Some water sensors only send alerts if the sensor comes into contact with water. But my sensor detected the water leak early enough that I could stop the leakage on time. It did not wait for the water to come into contact with its sensor to send alerts. 

I made the same observation with the LeakSmart Wi-Fi Sensor, which is incredible if you want to prevent sogging your floor. When buying your preferred smart water detector, I suggest you buy one that detects water too soon.

Power Source

You can be sure to find wired smart leak detectors. But battery-powered ones are my favorite. And that’s because they are easy to install and monitor your home around the clock. If you decide to opt for a battery-powered smart leak detector, check to see if its battery is powerful enough.

My smart water leak detectors rely on non-rechargeable batteries. But I like the batteries because they guarantee exceptional performance for at least two years. I found some smart leak detectors whose batteries lasted for five years. I recommend you buy a sensor whose battery lasts the longest.

You also have the option to buy smart leak sensors with rechargeable batteries. These sensors have a USB port through which you will charge their batteries. Also, some leak sensors allow you to place them on charging pads to top the batteries. If you can find these leak sensors that are super sensitive to responding to leaks quickly, you can make them your priority.


Another crucial point is how your smart water leak detector communicates with the connected devices. A smart leak sensor communicates with the app over your home wireless network at the primary level. When the smart water detector senses a pool of water, it sends an alert to your smartphone via the app. And this relies on Wi-Fi connectivity. 

At the same time, a smart leak detector communicates wirelessly with the connected devices, such as a shut-off valve. So, connectivity is a critical issue to consider before buying these devices. If you decide to integrate your smart leak sensor into your home, ensure its wireless connectivity supports the smart home hub.

I chose smart water leak sensors that use Wi-Fi connectivity because my house uses a Wi-Fi network to connect my smart home devices. You can find smart sensors that use ZigBee and Z-Wave on the market. 

Temperature Monitoring

A temperature-monitoring function is another feature you want from a smart water leak sensor. Besides, extreme temperatures damage the pipes, which could cause water leakages. 

You want to choose sensors with temperature-monitoring functions. But that’s possible if you have an excellent smart thermostat for your residential space. Smart water leak detectors such as LeakSmart Wi-Fi Sensor monitor the pipe water temperature. If the pipe water is freezing, I get a notification on my smartphone.

Humidity Monitoring

High humidity increases mold formation. You want to monitor the humidity level to keep it in check. Some smart water leak detectors monitor humidity for you. These sensors allow you to set them to send you alerts if the moisture falls out of a set range. These are the smart leak sensors you want to install in your home.

Compatibility with Accessories

The accessories I’m talking about are shut-off valve accessories. A shut-off valve connected with a smart water leak sensor over your home Wi-Fi network efficiently controls water flow to the fixtures. You can control the water supply to your fixtures by controlling the shut-off valve.

But the water leak sensor must be compatible with your chosen smart shut-off valve. So, if you want to add a shut-off valve to control the main water supply, it should connect seamlessly with your smart water leak sensor.

Integration With Smart assistants and Smart Hubs

You can connect your smart water leak detector with a smart hub to control other connected smart devices. Connecting the water sensor with a smart hub allows the hub to switch on the security alarm if water leaks onto the floor. Therefore, integrating the smart water sensor with a smart hub is essential.


You may need a smart leak detector to prevent potential water damage. No matter how observant you are, you will not notice leakages in tight places. You want to fix any broken pipe or appliance to prevent further leaking. If you don’t act fast and stop the leaking, you could be counting losses within a month.

Water leak sensor technology will detect any leakage and alert you to the location of the leakage. Also, it could pair with a smart shut-off valve to automatically switch the main water supply off if there is a leakage. Even more impressive, you can place the remote sensing disc of your smart sensor to detect leakage in tighter spaces. Since you can monitor every inch of your home with one of these smart leak sensors, installing the best leak sensor is good.
